NCIS: Los Angeles season 11 episode 16 is scheduled to air within a few weeks on CBS, with the title "Alsiyadun." The episode sees Fatima in a difficult situation, and guest star American rapper and songwriter Kiari "Offset" Cephus' character will be the one who could help her.

Just recently, CBS confirmed Offset will be appearing in NCIS: Los Angeles season 11 episode 16. He will have an essential role within this episode and will be a big help to Fatima (Medalion Rahimi). Although she is a skilled NCIS Special Agent, Fatima will need some help to get out of a difficult situation.

In NCIS: Los Angeles season 11 episode 16, Fatima was captured while doing a mission and was held for ransom. So, Callen (Chris O'Donnell) and Sam (LL Cool J) will enlist a deep undercover CIA agent named Kadri (Offset) to help her and get her back.

Meanwhile, CBS also confirmed earlier this year that Rahimi has been promoted as series regular. Now, it looks the episode is the first one for her as a series regular. In addition, it also seems to be the first to feature her following her departure on a mission earlier this season.

Rahimi's Fatima is smart, determined, got a unique skill set, and could do well in the office and out of the field. Although there is no indication of how she'll stay long-term, many were excited to find out what more she could offer now that she's a regular in the series.

In another related report, there is also another familiar face set to appear in the series. It has been confirmed that Bar Paly is back as Anna in episode 15. The character has been gone for a while, but she's frequently being mentioned this season.

While her whereabouts were unknown, Callen is determined to find her and track her down. And now, she returns in episode 15, but with a very particular reason. Anna came back to warn Callen that he is in danger and he needs to work with an archenemy to stop an underground trafficking ring.

Anna will have an important role in this episode, but there's no confirmation whether or not she'll stick around after this. Viewers are also hoping to see her and Callen having some romantic moments, especially since they have a history together.

NCIS: Los Angeles season 11 episode 16 arrives on Sunday, Mar. 1, on CBS.
